UNITED STATES PATENT OFFICE.

MIFFLIN \V. BAILY, OF POTTSTOW'N, PENNSYLVANIA.

STOVE-G RATE.

SPECIFICATION forming part of Letters Patent No. 341,209, dated May 4,1886.

Application filed August 24, 1885. Serial No. 115,213. (No model.)

To all whom it may concern.-

Be it known that I, MIFFLIN W. BAILY, of Pottstown, in the county ofMontgomery and State of Pennsylvania, have invented a new and ImprovedStoveGrate, of which the following is afull, clear, and exactdescription.

The object of my invention is to provide a new and improved stove-gratewhich facilitates the easy removal of ashes, cinders, 8:0.

The invention consists in arched grate-bars with horizontal outer edgesfor the retention of the coal, of a shaft provided with spearshapedfingers between the grate-bars, and of a device for moving thespear-shaped fingers between the grate bars.

The invention also consists of variousparts and details hereinafter morefully set forth and described.

Reference is to be had to the accompanying drawings, formingapart ofthis specificatiominwhich similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a vertical cross-section of my improvement on the line .r :rof Fig. 2. Fig. 2 is a longitudinalvertical section of the same on theline y yof Fig. 1, and Fig. 3 is a crosssection of one of the spearshaped fingers.

The fire'boX A is provided with the downwardlyextending arms B, on thelower edges of which rest the side bars, O O, on which are mounted thegrate-bars D. The grate-barsD consist of the arched part, D, terminatingat each side in the horizontal parts, D which rest with their loweredges on the side bars, C C.

Between the top edge of the horizontal parts D of the grate'bars D andthe bottom edge of the fire-box A is formed a space, B, of sufficientheight to allow the discharge of the cinders over the edges of thehorizontal parts D of the grate-bars D. The space B is formed betweenthe arms B, the top edge of the grate-bars D, and the bottom edge of thefire-box.

Centrally below the grate-bars D is mounted the shaft E in hangers F,secured to the ends of the firebox A in any suitable manner. The shaft Eis provided with the diamond or spear shaped fingers G, placed in thespaces formed between the grate-bars D. The upper end of the fingers Grest on either of the side bars, G, and can be moved from one side bar 0to the other, by oscillating the cr'anle arm H, attached to one outerend of the shaft E.

When the fingers G are at rest, as shown in Fig. 1, the upper ends ofthe same do not extend beyond the top edge of the grate-bars D; but whenmoved toward the center of the arched part D the upper ends of thefingers G project beyond the top edge of the gratebars, but do not quitereach to the bottom of the fire-box A. It will thus be seen that whentheshaft E, and consequently the fingers G, are oscillated by means of thecrankarm H, the sharp edges of the upper end of the fingers G willeasily cut through the fuel on the top of the grate bars D andeffectually clean the fuel, causing the ashes and cinders to fallbetween the grate-bars D, or be pushed through the space B, over theedges of the horizontal parts D of the grate-bars D, and fall into theash-pit.

By providing the fingers with spearshaped heads, or heads which arediamond shape in cross-section, cuttingedges are formed which will outeasily through the fuel, thereby permitting them to be more easilyoscillated between the grate'bars. The contraction of the fingers attheir upper ends, and forming heads thereon of the character described,also permit the ashes to more readily escape to the ash-pit.

Having thus described my invention, I claim as new anddesire to secureby Letters Patent-- 1. In a stove-grate, the gratebars D and the sidebars, 0 O, in combination with the .shaft E, and the diamond or spearshaped fingers G, substantially as shown and described.

2. In a grate-bar, the combination of a firebox having a space, E, theside bars, 0, and the arched grate-bars D, with diamond or spear shapedfingers E, mounted on ashaft and extending between the said g1'atebars,substantially as shown and described.

3. In a stove-grate, the combination of the arched grate bars D with theoscillating shaft E, and the spear-shaped fingers G, mounted on saidshaft E and placed alternately between the grate-bars D, substantiallyas herein shown and described.
